We are told this journey will be a roller coaster ride and the last two days have been our first set back. Grey has been having trouble on the ventilator. She is oxygenating well but ventilating has been an issue, causing elevated CO2 levels. They tried to switch her to an oscillator – a type of vent that expands and flutters the lungs rather than providing single breaths. This is more commonly used on smaller preemies as their lungs are not usually developed enough to handle the tradition ventilators. It is loud and looks very aggressive, rattling Grey in her incubator. It was the first time we really saw her very upset and it was heartbreaking to watch (though they say it is easier on the lungs). However, after a night on the oscillator her labs did not improve under acceptable vent levels and she was moved back to the traditional vent. The doctors continue to make adjustments trying to get her CO2 and blood acidity levels under control.
On a positive note, she also started regular feeding with breast milk through her OG (tubing ran through her mouth to her stomach). She continues to be supplemented with nutrition through her IV as well. She has handled the feeding well and increased her volume over the last three days. Hopefully these added calories will help her grow and develop her lungs for better breathing results.
